Usually, it can be hard to picture the difference in sensor measurements purely by checking out specifications. The visual here might offer you a better sense of the sensor sizes in the E-PL9 and 645Z.

Plainly, the two cameras posses different resolutions and different sensor measurements. The E-PL9 with its smaller sensor is going to make achieving shallower DOF trickier and the Pentax 645Z will provide more detail having an extra 35 Megapixels. Higher resolution will let you crop shots somewhat more aggressively. The more modern E-PL9 should have an edge with regard to sensor technology.
